  • f6c90b71a   [NET]: Fix ipx/econet/appletalk/irda ioctl crashes ... Browse Code »

    Fix kernel oopses whenever somebody issues compatible ioctl on AppleTalk,
    Econet, IPX or IRDA socket. For AppleTalk/Econet/IRDA it restores state
    in which these sockets were before compat_ioctl was introduced to the socket
    ops, for IPX it implements support for 4 ioctls which were not implemented
    before - as these ioctls use structures which match between 32bit and 64bit
    userspace, no special code is needed, just call 64bit ioctl handler.

  • b5e5fa5e0   [NET]: Add a dev_ioctl() fallback to sock_ioctl() ... Browse Code »

    Currently all network protocols need to call dev_ioctl as the default
    fallback in their ioctl implementations. This patch adds a fallback
    to dev_ioctl to sock_ioctl if the protocol returned -ENOIOCTLCMD.
    This way all the procotol ioctl handlers can be simplified and we don't
    need to export dev_ioctl.

  • 90ddc4f04   [NET]: move struct proto_ops to const ... Browse Code »

    I noticed that some of 'struct proto_ops' used in the kernel may share
    a cache line used by locks or other heavily modified data. (default
    linker alignement is 32 bytes, and L1_CACHE_LINE is 64 or 128 at
    least)

    This patch makes sure a 'struct proto_ops' can be declared as const,
    so that all cpus can share all parts of it without false sharing.

    This is not mandatory : a driver can still use a read/write structure
    if it needs to (and eventually a __read_mostly)

    I made a global stubstitute to change all existing occurences to make
    them const.

    This should reduce the possibility of false sharing on SMP, and
    speedup some socket system calls.

  • 64233bffb   [APPLETALK]: Fix broadcast bug. ... Browse Code »

    From: Oliver Dawid

    we found a bug in net/appletalk/ddp.c concerning broadcast packets. In
    kernel 2.4 it was working fine. The bug first occured 4 years ago when
    switching to new SNAP layer handling. This bug can be splitted up into a
    sending(1) and reception(2) problem:

    Sending(1)
    In kernel 2.4 broadcast packets were sent to a matching ethernet device
    and atalk_rcv() was called to receive it as "loopback" (so loopback
    packets were shortcutted and handled in DDP layer).

    When switching to the new SNAP structure, this shortcut was removed and
    the loopback packet was send to SNAP layer. The author forgot to replace
    the remote device pointer by the loopback device pointer before sending
    the packet to SNAP layer (by calling ddp_dl->request() ) therfor the
    packet was not sent back by underlying layers to ddp's atalk_rcv().

    Reception(2)
    In atalk_rcv() a packet received by this loopback mechanism contains now
    the (rigth) loopback device pointer (in Kernel 2.4 it was the (wrong)
    remote ethernet device pointer) and therefor no matching socket will be
    found to deliver this packet to. Because a broadcast packet should be
    send to the first matching socket (as it is done in many other protocols
    (?)), we removed the network comparison in broadcast case.

    Below you will find a patch to correct this bug. Its diffed to kernel
    2.6.14-rc1

  • c752f0739   [TCP]: Move the tcp sock states to net/tcp_states.h ... Browse Code »

    Lots of places just needs the states, not even linux/tcp.h, where this
    enum was, needs it.

    This speeds up development of the refactorings as less sources are
    rebuilt when things get moved from net/tcp.h.

  • f2ccd8fa0   [NET]: Kill skb->real_dev ... Browse Code »

    Bonding just wants the device before the skb_bond()
    decapsulation occurs, so simply pass that original
    device into packet_type->func() as an argument.

    It remains to be seen whether we can use this same
    exact thing to get rid of skb->input_dev as well.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
